PET skylight tiles are made of PET as the base material and fiber cloth as the skeleton. They are more environmentally friendly, durable and have higher light transmittance than FRP boards, and have lower costs than PC boards. While ensuring the high light transmittance of PET boards, they avoid the defects of high temperature deformation. The light transmittance can reach 83%, and the high temperature resistance can reach 120 degrees Celsius. They can be used outdoors for more than 10 years.
